Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001] The present invention generally relates to a portable surveillance camera and a personal surveillance system using the same, and more specifically, to a portable surveillance camera having an embedded mini-camera such as a CMOS camera or a CCD camera, and a system for surveilling a specific place using the portable surveillance camera. Also, the present invention relates to a personal surveillance system for receiving multimedia data such as image, sound, event and control data on real time from a portable surveillance cameras installed in various areas such as a house, a store, an office with a control device connectable to a network (i.e., LAN, intemet, etc.) to monitor or store the multimedia data, for searching, surveilling, controlling, editing and storing multimedia data (i.e., image, sound, event, control data) for a desired period of time from the data stored in the portable surveillance camera or the control device. BACKGROUND ART [0002] A closed circuit TV (abbreviated as "CCTV") and a video cassette recorder (abbreviated as "VCR") have been widely used as a conventional security and surveillance system. The VCR used for recording image in the CCTV receives an analog video signal as a PAL or NTSC type from a surveillance camera, and processes the analog video signal to be recorded in a magnetic tape of a video cassette depending on a VHS or SVHS standard. [0003] Since the conventional VCR records the received analog video signal as an analog recording signal on a basis of the analog recording standard, a video cassette tape is repeatedly used, which results in degradation of image quality, change of surveillance image, only support of sequential search, trouble in configuration with more than 3 equipments, inconvenience of recording tape and need of a resident surveillant. [0004] A digital video recorder (abbreviated as "DVR") is provided to solve the problems in a processing and storing method of an analog recording signal. Since the DVR is based on a digital data processing system, multi-channel video signals inputted from a plurality of video cameras are represented at one time on 4 or 16 screens obtained by dividing one monitor screen, or a screen of a desired surveillance area is displayed as a single screen on the whole screen of the monitor. As a result, it is easy to provide various functions in the DVR. [0005] A detection sensor is installed to surveille the circumstance or intrusion of a foreigner in every surveillance place. When an event is detected through the detection sensor and an alarm is inputted while a surveillance area is displayed on the divided screens, it is easier to embody various functions such as an automatic conversion function to display a screen of a corresponding surveillance area by adding hardware and software to a dedicated control device. Also, it is possible to minimize storage capacity by applying image and sound information of the screen to an enhanced compression technique, and it is easy to store, keep and search data. As a result, the DVR has been widely distributed. [0006] Although various technologies have been developed on a basis of processing of digital data for a security surveillance system, these surveillance systems have a limitation which depend on a method of receiving data such as image, sound and event signals by detection of a sensor on a wire from a plurality of surveillance cameras positioned in fixed locations in control devices such as a dedicated control device and of transmitting and receiving various control signals. Also, it is improper to use for personal surveillance systems which frequently move due to configuration of the systems and its size. For example, when a person who frequently moves intends to surveille various crimes or risks in a predetermined area where the person stays such as an office or a house, and to record the situation at emergency, the surveillance cameras should be installed in all areas where the person stays. As a result, excessive cost is required in installment and operation of the system so that it is impossible for a person to install and operate the system. [0007] In order to solve the above-described problem, `a security system and method using a visual portable phone` in the Korean Patent Application No. 10-1999-0052960 discloses a configuration where a sensor is mounted in a portable wireless phone having a camera which has been widely used to transmit data to a control device through a repeater and to contact with a security company at emergency. [0008] However, the conventional system with a portable wireless phone having a camera and a wireless phone network have a limitation in transmission capacity of data. Additionally, while a user uses the basic functions of a phone such as calling and receiving a message, the user cannot use a surveillance function. Since data are transmitted to a central processing unit through a wireless phone network, the surveillance function cannot be performed in an area where connection of the wireless phone network is not smooth. Besides, it is difficult to unite various additional functions required in a surveillance camera because a wireless phone is used. Here, a system is required which includes a large-scaled server for receiving data through the wireless phone network and processing in the center. As a result, an operating subject cannot but be a large-scale communication company having a plurality of subscribers so that it is necessary to construct a large number of infrastructures before an individual can receive the service.

DETAILED DESCRIPTION OF THE INVENTION Technical Subject [0015] In order to solve the above-described problems, it is an object of the present invention to provide a portable surveillance camera which is capable of being instantly installed in a desired location by person who frequently moves without installment of an additional security camera and a CCTV system, of being portable to be changed in its location and of being united into a personal surveillance camera dedicated device for embodiment of various functions such as addition of a sensor to be proper for personal surveillance, and a personal surveillance system using the same. [0016] It is another object of the present invention to provide a portable surveillance camera having a function of storing multimedia data therein so that the data is stored and kept in a place having an unstable or incomplete network or wireless net, and a personal surveillance system using the same. [0017] It is still another object of the present invention to provide a portable surveillance camera for transmitting and storing data by a local area wireless communication protocol to a control device on real time which has various functions performed in the portable surveillance camera except a control function so that the control device can perform a function of the surveillance camera if necessary, and a personal surveillance system using the same. [0018] It is still another object of the present invention to provide a personal surveillance system which enables itself to surveille, search, control, edit and store data remotely through network such as LAN or intemet connected to the control device.
